The puff prot of described door font rotary jet pipe is for axially being opened in the groove on its tube wall along described transverse tube, standpipe, the notch of described groove is offered towards described screen drum direction.
The puff prot of described door font rotary jet pipe is for arranging the bar hole that is opened on its tube wall along described transverse tube, standpipe axially spaced-apart, and the aperture of described bar hole is offered towards described screen drum direction.
The door font rotary jet pipe that is arranged on zone between described screen drum and the casing is two, the mutual square crossing setting of transverse tube of described two door font rotary jet pipes.
Advantage of the present invention is mainly reflected in following several respects:
1, the powder screening process is taked air current classifying to combine with screen fractionation to carry out simultaneously, by being arranged on the outer door font rotary jet pipe of screen drum, produce uniformly, blow to the air-flow in the screen drum at the screen drum outer peripheral face, stop micron order material in light weight, that particle diameter is little and piled up the generation that forms caking and cause the sieve pore blockade phenomenon at screen cloth, improved the classification efficiency of powder greatly; Therefore, handle (diameter of particle after the processing≤25 micron) for the ultramicronising of powder technical guarantee is provided, thereby make the screening work of the above ultra micro powder of 500 orders be able to large-scale industrial production;
2, because the structural design of screening machine of the present invention make screening part can select the screen drum structure, and under the condition of screening plant given volume, the sieving area of screen drum is bigger than the sieving area of sieve plate, has improved screening efficiency.
3, the present invention adopts air-introduced machine air-flow directing material to sieve, and like this, again material is produced air-dry effect in screening, has saved the peripheral hardware drying plant, has reduced consumption reduction;
4, simple in structure, the screen drum of screening machine of the present invention change convenient, for ease of maintenaince and maintenance.
